Lette/rs Patent No. 92,312, dated July 6, 1869.

IMPROVEMENT IN ROPE-MOULDING- MACHIN.

The Schedule referred to in these Letters Patent and making part f the same.

To all whom it may concern:

Be it known that I, NOAH WILLIAM Housn, of Adrian, in the county of Lenawee, and State of Michigan, have invented a new and useful Improvemeut'in Rope-Moulding Machines; and I do hereby declare that the following is a clear and exact' description,

which. will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, and to the letters marked thereon, making a part of this specification. v 'f My invention consists in providing a hollow mandrel with one or more radial diesor cutters, arranged 011 a section ofthe face-plate, behind which is a bore spil-ally grooved, precisely similar to that formed by casting metal around ihe moulding, the object of the spiral bore being to draw the moulding with uniform speed through and between the cutters while cutting it; also, in the construction of the several parts which constitute the machine, and in peculiar and novel devices by which they are attached one to theother; and furthermore, in providing within the die-plate- 'back of the oblique knives, double spiral grooves, for

the purpose hereinafter stated.

In the drawings- Figure l is a 'perspective viewof a rope-moulding y machine embodying my invention. Y

Figure 2 is a verticalv section of the moulding-machine, passing longitudinally through theentre of the mandrel-shaft.

Figurel 3 is a section of the die-plate of the mandrel, when viewed in the line ofthe mandrel-shaft, and contains, among other things, a view of the two slots for fastening this section to the face-plate.

Figure 4 presents a view of a longitudinal section of one of .these slots.

Figure 5 shows the division-lines between the face plate of the'maudrel, the section containing the spiral bore, viz, thc die-plate, 'and the nose-piece of the machine. n v r v Figure G is a perspective view ofthe cutter-head. of

. the mandrel, and is to be used for rounding the timber preparatory to cutting the moulding thereon'.

In lig.' l of the drawings, E and "F represent the 4 mandrelshaft, and A thebaud-wheel for vdriving the' same. -B represents the face-plate of l the mandrel-v sbaft C, the die-plate; D, the nosepiece; x. and y, the journalboxes;` b, one ofthe dies or cutters; vGr, one of the holes through which toilet the'shavings pass; and la and l, screws by which the nose-piecc-D `is secured io the die-plate C. H is the frame that supports the machine.

In rigs. 2 and 3, ab represent the dies or cutters',

and c ll, the loop-bolts for securing them to' their respective place on the die-plate.' c represents the spiral bore. L l. 4

In iig. 3, f G represent the' openings through which the shavings pass out; h l, the slots by which the. dieplate G is secured to the face-plate B; l.' l, holes to admit the screws which connect the nose-piece D to the die-plate C. v

' In fig. 4, a' is the opening, and c the inclined plane of the slots, represented by h and t' in g. 3.

The dic-plate c is constructed so as to be readily (letached from the face-plate B in the following manner:

Press one hand on the band-wheel A, so as to prevent it from turning; then clasp the die-plate C rmly with the other hand, and turn it slightly in the direction indicated by the arrow a. In this way the clutches S and T, in figs. 5 and 6, are brought through the slots .h and l (tig. 3) to the openings l',`(gs. 3, 4, and 6,)

down the inclined plane c', fig. 4.

In the same manner the cutter-head of the mandrel,

m, fig. 6, is readily attached to or detached from the face-plate B, iig. l.

The material to be 'turned into rope-moulding is y first to be rounded and brought to theproper thickhess by being passed through the rounder m. To accomplish this, the die-plate O is detached from the face-plate B, and the rounder m secured in lieu thereof. The machine is now ready to round the material preparatory to being turnedv into moulding. When suicient material has thus been rounded, the rounder is removed, and the die-plate O again attached, when the machine is ready for turning.

It is designed to out any desirable size of mouldings with the same machine, by having suitable-sized dieplates and rouuders for each size of moulding.

It is alsodesigned to have one ormore cutters, corresponding to the number of threads or leaders desired on 'the moulding.

The timber, when rounded the size requisite, is introduced into the nose-piece D, throughthe leader F. This leader is a smooth bore, just large enough to admit of the entrance of the round on which it is desired to cut the moulding, and thereby keeps the material, while being acted upon, `central with the edges of the cutters and spiral bore behind.

The bore c, behind the cutters, isspirally gropved, and an exactcounterpart of the moulding after it has left the knives. The purpose of this spirally-grooved bore is to facilitate the action of the knives uponthe material. When the material enters theleader F, the

bore of which being smooth, and just largey enough to, receive it, it is necessarily held centrally to the edges of the cutters; but after the material has been acted upon by the knives, it is no longer round, but screwformed, and requires something to keep it in a direct line with the cutting-edgesof the knives, and to regand is constructed upon any of 'the Well-known plans of the hollow niandrels; the niodeof fastening it to the face-plate being the only novelty claimed.

Figure 7 shows a longitudinal section of one of the loep-bolts c or (l, represented in fig. 3, and when thus viewed in the direction in which the cutters pass through it, it shows the opening a'.

b is the screw, and c, the nut, which, screwed tightly against the back of the die-plate, holds the cutters tirinlyjn the places made for that purpose in the die-plate.

By means of the nut c and loop-bolts c and d, the

cutters can be easily placed in Working-position, both loop-bolts being constructed alike.

Both the die-plate C and the rounderon are fastened to the faceplate B in the same manner, to wit, by means of the clutches S and T, and the slots h and i, their tendency being (onvaccount of the inclined plane c, iig. 4) to draw tighter to the face-plate when the faceplate is turned in the direction for cutting m'ouldings.

In the drawings, the style of moulding contemplated is that of an oval-shaped strand; but it is nevertheless designed (with suitable-shaped cutters and spiral) to cut inouldings of any other style of strands.

The red lines 1, 2, 3, and/4, shown in figs. 2, 3, 4, and 5, represent projections of the face-platc B and die-plate C. Said projections entercorresponding cavon its side against which the'die-plate abuts, a cavity, .4, just suiiciently large enough to receive the projection 3 of the die-plate C. In the same manner 'the face-plate B enters upon the die-plate O, and the rounder m upon the face-plate B. This arrangement guarantees the cent1-ing of the different parts, one upon another, and prevents accidentaldisplacement.

Having described my invention, I claim as new therein, and desire to secure by Letters Patentl. A machine for cutting rope-moulding, provided with a face-plate, B, dieplate C, nose-piece D, oblique knives a b, and spiral grooves e, arranged, connected,

and operating ,substantially as and forthe purposes herein described.

2. The face-plate B, die-plate C, an'd nose-,piece D, in combination with the clutches S T, slots h i, and projections and depressions l, 2, 3, 4, substantially as described. ,l

- NOAH WM. HOUSE.
